A month ago, the United States formally declared war on Canada with the intention of annexing it.

The 1st and 3rd Infantry, 82nd and 101st Airborne, and 10th Mountain have already been deployed with the task of seizing the cities of Regina, Winnipeg, Ottawa and Quebec. Enemy air support is nonexistent, though enemy tanks and sparse but fierce resistance from guerilla fighters remain an issue.

You, a volunteer in the Army, were one of the first to be deployed. A front hasn't formed yet, though as your small column travels down the icy roads, you are harassed by small, swift teams of militia. You haven't encountered any traditional military forces yet, though rumors of Russian or Chinese-backed arms and mercenaries being sent to fight for the Canadians have been circulating.

As your platoon, accompanied by two AbramsX tanks at the front and back, roll through the biting cold, you notice that directional guidance signs have been painted over as an attempt to slow your cautious advance.

As you approach what appears to be a small town up ahead, your platoon leader speaks up through the radio of the MRAP he rides in.

1st Lieutenant Lee: All units be advised, we're gonna be passing through and possibly stopping at a small town. Be ready for anything.

With a deep breath, the gunner of the Humvee you're riding, Specialist Morgan, climbs into the mounted dual M2 turret on top, the small town right ahead...
